摘要
根据黄河流域2011—2020年省级面板数据,运用熵权法从资源利用、环境影响、生态保育和经济效益等4个方面对该流域整体及各区域农业绿色发展水平进行评价,并进行区域性差异分析。结果表明:(1)黄河流域整体农业绿色发展水平综合得分并不高,且整体表现出上升趋势,仅在2018年出现了降低。从分类指标来看,各分类指标之间的得分具有较大的差异,资源利用的得分最高,环境影响的得分最低,生态保育和经济效益的得分虽低于资源利用,但三者之间的差别并不大。(2)下游地区农业绿色发展水平综合得分均值最高,中游次之,上游得分最低。从发展趋势来看,上游地区在样本期间内整体表现出上升趋势,但仍存在波动,中游地区相对较为平稳下游地区农业绿色发展水平得分均值虽最高,但其发展趋势的波动性明显大于上游和中游。
Based on the provincial panel data of the Yellow River basin from 2011 to 2020,this paper uses the entropy weight method to evaluate the overall and regional agricultural green development level of the Yellow River basin from four aspects of resource utilization,environmental impact,ecological conservation and economic benefits,and carries out regional difference analysis.The results show that:①The overall agricultural green development level of the Yellow River basin is not high and shows an overall upward trend,only in 2018 did it decrease.From the perspective of classification indicators,the scores of each classification indicator are quite different.The score of resource utilization is the highest,the score of environmental impact is the lowest,and the score of ecological conservation and economic benefits is lower than that of resource utilization,but the difference between the three is not significant.②The average comprehensive score of agricultural green development level in the downstream region is the highest,followed by the middle reaches,and the lowest in the upstream region.From the perspective of development trend,the upstream region shows an overall upward trend during the sample period,but there are still fluctuations.Although the average score of agricultural green development level in the relatively stable downstream region is the highest,the volatility of its development trend is significantly greater than that in the upstream and midstream regions.
